T-Mobile is joining the party, as we knew they would, and will start selling the Samsung Galaxy Tab 7" Android tablet running Froyo on a 1GHz Hummingbird CPU. The Tab will set you back $399 on T-Mobile if you get it with a 2 year contract.

The Tab has 3G HSDPA and WiFi as well as Bluetooth and if you can imagine a super-sized Samsung Vibrant, the Tab is all that. Bundled apps include Amazon Kindle reader, Qik Video Chat, Asphalt 5 HD racing (demo game) and Samsung's pretty solid Media Hub that competes with iTunes for movie and TV show rentals and purchase.
